Digital Camera World Verdict

The Olympus M.Zuiko 40-150mm f/2.8 Pro is one of my favorite lenses, and one of the best at what it does. For photographing wildlife on safari, I simply could not be without it; it's half the size and weight of most full-frame 70-200mm equivalents and, with an effective 300mm at the long end, offers much more reach as well. Its tiny size and weight combined with the gobsmackingly good image stabilization of Olympus / OM System bodies makes it my preferred weapon for telephoto shooting – particularly with the IP53 weather sealing and 2x teleconverter compatibility (giving it a 160-600mm effective range!). It also has the coolest lens hood I've ever seen!

The Olympus M.Zuiko 40-150mm f/2.8 Pro is one of the workhorse Olympus / OM System lenses, and for good reason – it's a lens I simply cannot be without. I'm lucky enough to have used this lens around the world, both on paid commissions and for personal work, and it's an absolute kitbag essential.

The focal range of the Olympus M.Zuiko 40-150mm f/2.8 Pro is unfamiliar, due to the 2x crop factor of Micro Four Thirds (MFT) cameras, but this is effectively a 70-200mm f/2.8 trinity lens. Except, of course, that said crop factor actually makes this an 80-300mm trinity lens, in a form factor that's smaller and lighter than any full-frame equivalent.
